Coex 3D Filament Settings

COEX 3D print settings by material

These are COEX 3D's recommended starting settings for the filaments we make in Green Bay, Wisconsin. All temperatures are in °C. Treat each range as a starting point and adjust it for your printer. On high-speed printers such as Bambu Lab, raise the nozzle temperature by 5–15°C. Every COEX spool ships dried and vacuum-sealed. Dry it again only after it has been exposed to air.

Settings by material

  • PLA: Print COEX PLA with a 220–240°C nozzle and a 0–60°C bed, with the part-cooling fan up to 100% (off for the first layer), and dry it at 55°C for 3–6 hours.
  • PLA Prime: Print PLA Prime with a 220–240°C nozzle, a 0–60°C bed and the fan up to 100%, and dry it at 55°C for 3–6 hours.
  • PLA+Silk: Print PLA+Silk with a 220–240°C nozzle, a 0–60°C bed and the fan up to 100%, and dry it at 55°C for 3–6 hours.
  • ABS: Print COEX ABS with a 245–265°C nozzle, a 90–110°C bed and an enclosure, with the fan at 0–30% (off for the first layer), and dry it at 80°C for 4–6 hours.

Key Printing Notes & Pro Tips for Coex Filament Settings

Proper Coex Filament Settings are essential for achieving outstanding results with your 3D prints. Choosing the right parameters helps you optimize print quality and avoid issues. To get the best from your filament, follow these detailed notes and suggestions for setting up your 3D printer.

Optimizing High-Speed Printing

  • For high-speed printers, especially models such as Bambu Lab or similar brands, standard settings may not be enough. High flow rates can challenge your printer and the filament may not melt thoroughly when passing quickly through the hotend.
  • As a result, consider increasing the recommended hotend temperature by 5-15°C. This adjustment ensures that filament melts completely and allows for proper bonding between layers even at higher speeds.
  • These adjustments to your settings help to prevent under-extrusion and promote strong layer adhesion. It is always a good idea to perform test prints after each change, so you can observe improvements and fine-tune your setup.

Importance of Drying - Advanced Filament Care

  • Materials such as Nylon, PETG, ABS, and ASA are highly hygroscopic. This means they absorb moisture from the surrounding air quickly and easily.
  • Coex 3D takes great care to dry every spool before packaging, but maintaining this dryness is your responsibility after opening. Always store filament in a sealed bag or container with desiccant packs.
  • Dry filament is critical for achieving warp-free prints and strong, consistent layers. If you notice prints deteriorating or hear popping while printing, dry your filament using a dedicated filament dryer or a low-temperature oven designed for 3D printing materials.

Maintaining Your Nozzle for Longer Life

  • Some filaments, such as Coex’s PA6-CF Carbon Fiber Nylon, are abrasive and will significantly wear down brass nozzles.
  • You must use a hardened steel, ruby-tipped, or other wear-resistant nozzle when printing with these materials. Regular nozzles will wear out quickly, leading to poor print quality and failed prints.
  • Replacing your nozzle before beginning a large print or an important project is smart. This practice can save you valuable time and resources.

Release Agents & Print Removal with Coex Filament Settings

Some materials, including PETG, PCTG, and COEXFLEX, create an extremely strong bond to glass or smooth PEI printing surfaces. This intense adhesion can cause prints or build plates to break upon removal if not managed properly through your settings.

  • Always use an appropriate adhesion material such as a glue stick or WELD3D when printing with strong-bonding filaments. These products provide a controlled release during print removal, preventing both print and surface damage.
  • Apply these release agents before each print, especially with new filament types or when changing your device setup. This enhances your workflow and increases the longevity of your equipment.

How to Set Up My Device for Best Results

Regularly review your settings and make gradual adjustments to gain the best possible print quality. Small changes to your nozzle temperature, print speed, and cooling can have a big impact on your project.

Use the settings app or your printer’s interface to save and recall profiles for each filament type. This practice allows you to quickly switch between different materials and production needs without starting from scratch.

Additional Tips: Getting the Most from Coex Filament Settings

Keeping track of your print environment is essential. Room humidity and temperature affect filament performance. Store spools properly and monitor the ambient conditions in your workspace to ensure consistency.

Refer to the tables above as a guide while adjusting your Coex Filament Settings. Whether you are new to 3D printing or an experienced user, revisiting these basics will save you time and materials.

Don’t hesitate to experiment with minor adjustments based on your printer model and workload. You will find your personal best settings through careful trials and attentive monitoring of print results.

By following the outlined tips and focusing on correct Coex Filament Settings, you will consistently achieve strong, precise, and attractive 3D prints. Make careful adjustments, stay organized, and enjoy exploring new materials and creative possibilities!
